The Chevrolet Volt is also stirring buzz. The five-door sedan is one of several electric cars on display boasting a lithium battery and a gasoline-powered engine. The Volt can run on electric power for 40 miles. Then, the gasoline engine kicks in to recharge the battery, allowing Volt owners to travel hundreds of miles more.

"Electrifying our vehicles is a key strategy," said Pete Barkey of GM.

Among the more eye-catching displays belongs to Ford's 2010 Taurus. Set on a clamshell-shaped stage, the Taurus body opens up with the press of a button, revealing its engine and interior.

While smaller, more fuel efficient cars occupy the most space, the show at the Jacob Javits Convention Center still offers its share of extravagant and extraordinary vehicles.
